Summary
-
1.
The polychromatic staining of plant cell walls by toluidine blue O is described and illustrated.
-
2.
The effects of various common fixatives and the effects of the pH of the staining solution are evaluated.
-
3.
Simple and rapid procedures are described for preparing stained temporary mounts of fresh material, or permanent mounts of embedded and sectioned material.
-
4.
The relationship between the polychromatic staining observed and the lignification of the walls is discussed.
